U-CONTROL UMX25
4. OPERATION
The eight buttons B1 – B8 generate switch controllers.
Again, these are factory-set functions (see table on
the device). Like the rotary controls the buttons can be
freely assigned to any controller in ASSIGN mode.
The table shows the controller assignment preset at the
factory.
Keyboard legend: Informs you about the special functions
performed by individual keys on the keyboard. The
individual elements of the keyboard legend are described
in detail in Chapter 4 “OPERATION”.

Use this socket to supply the UMX25 with current from an
external power supply unit (not included).
The USB connector of the UMX25. The connector (type B)
on the device is connected using the cable supplied to a
free slot on the host computer (where you will find a type A
connector). It is compatible with the USB 1.1 and
USB 2.0 standards.

In addition to the connection to the computer, you can use
the MIDI OUT to connect additional MIDI devices, so that
the UMX25 transforms into a fully-featured, easily
accessible MIDI interface for your host computer.
Use the FOOT SWITCH connector to connect a sustain
pedal. This port is factory-set and assigned to the MIDI
parameter “Foot Pedal” (CC 64), which represents a switch
controller. When the pedal is pressed (and held) in normal
Play mode, it generates a controller with the value 127.
When the pedal is released, the controller falls back to 0
(typical piano sustain pedal behavior). Apart from that the
pedal assignment is the same as the button assignment,
i.e. you can assign any MIDI controller to it.
The POWER switch is used to switch the unit on and off.
Please close all programs if you want to switch off
the UMX25 while the computer is running or
terminate the USB connection.
4. OPERATION
In the following, we will explain the operation of the UMX25 in
detail. Please note the differentiation between buttons (see
control elements ) and keys (control element )! Please
do not confuse these!
4.1 PLAY mode
After power-up the UMX25 is in PLAY mode. You can start
playing, modify filter sweeps with the rotary controls, determine
program changes intuitively, realize panorama changes, control
soft synths, and so on.
4.1.1 The FACTORY MEMORY
The FACTORY MEMORY is the internal memory storing the
basic settings of the UMX25. The most important feature of the
FACTORY MEMORY is the controller map described in point .
These settings define a number of useful parameters and are
automatically loaded when the device is switched on.
Assignments that are modified during a session, will be
discarded when the unit is switched off. In order to save the
modified assignments, the UMX25 has been provided with a
USER MEMORY.
